CWDM system is able to provide optical networking support for high-speed data communication for metropolitan area networks (MANs). And in some previous articles, I have talked a lot about CWDM, such as the components used in CWDM system. In this article, I’d like to have an introduction to CWDM system installation and connection. Procedures for […]

Introduction to the Components Used in CWDM System
CWDM system is a passive optical solution for increasing the flexibility and capacity of existing fiber lines in high-speed networks. It increases fiber capacity by placing widely spaced, separate wavelengths (between 1310 nm and 1610 nm) from multiple ports onto a single-mode fiber pair on the network. The CWDM system components are passive and require […]
Introduction to the Components Used in DWDM System
DWDM is an innovation that enables multiple optical carriers to travel in parallel in a fiber. DWDM devices combine the output from several optical transmitters for transmission across a single fiber. At the receiving end, another DWDM device separates the combined optical signals and passes each channel to an optical receiver. Only one optical fiber […]
Understanding the Split Ratios and Splitting Level of Optical Splitters
Optical splitters play an important role in FTTH PON networks where a single optical input is split into multiple output, thus allowing a single PON interface to be shared among many subscribers. The optical splitters have no active electronics and don’t require any power to operate. They are typically installed in each optical network between […]
Traditional CWDM Mux/DeMux vs. FMU Series CWDM Mux/DeMux
With the need for bandwidth increases, the WDM (wavelength division multiplexing) technology was developed to expand network capacity over a single fiber. It uses a multiplexer (Mux) at the transmitter to combine several signals together, and a demultiplexer (DeMux) at the receiver to split them apart. Most WDM systems operate on 9µm single-mode fiber optical […]
FBT Splitters vs. PLC Splitters: What Are the Differences?
Fiber optic splitters play an increasingly significant role in many of today’s optical network topologies. They provide capabilities that help users maximize the functionality of optical network circuits from FTTx systems to traditional optical networks. And usually they are placed in the central office or in one of the distribution points (outdoor or indoor). This […]
